摘要：The method involves varying the frequency of the transmitter laser (SL) and measuring the transmission quality of a data channel at the receiver side. The frequency of the transmitter laser is controlled to achieve the optimal transmission quality. The frequency of the transmitter layer is experimentally varied by a control device (RE1), and the corresponding reception signal (DSE) is evaluated. The frequency of the laser may be swept and controlled based on the lock-in principle. As a criterion for transmission quality, the channel error rate of the received signal, the signal-to-noise ratio or the power of the received signal is used.
